Retrieves the specified number of items in the enumeration sequence.
HRESULT Next( ULONG cMediaTypes , AM_MEDIA_TYPE** ppMediaTypes , ULONG * pcFetched );
Parameters
- cMediaTypes
- Number of media types to place.
- ppMediaTypes
- Array in which to place the next media type or types.
- pcFetched
- Actual count passed.
Return Values
Returns an HRESULTvalue.
Remarks
This member function implements the IEnumMediaTypes::Nextmethod. To call this method, pass a pointer's address to a media type. The base class implementation relies on the existence of an overridden CBasePin::GetMediaTypemember function in the derived class that will provide the next media type.
Free each media type acquired by calling DeleteMediaType, which will free the format block and the media type itself.
